Abstract
Abstract A tile for use in constructing an entrance mat. The tile has a flat base and low walls surrounding the base for retaining water on the base. Scraper means are provided on the base for scraping snow, water and/or slush off the feet of people using the mat. Means are provided on each wall for use in connecting the tile to an adjacent tile. A plurality of the tiles are connected together to form a mat. Means are provided in each wall of a tile for directing water out of the tile when it reaches a certain level. The invention is also directed toward a mat made up of a plurality of the tiles.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
225 words
A tile having a flat imperforate base with a top surface and a shape defined by straight sides, said tile comprising low straight walls protruding from said top surface along each side of the base, said wall forming the entire perimeter of the base to hold water on the base, means for use in removably connecting the tile to adjacent identical tiles to form a mat with the outside surface of a straight wall of the tile abutting the outside surfaces of the straight walls of adjacent tiles, scraper members upstanding from and uniformly distributed over said top surface within the confines of said wall, the scraper members comprising a series of spaced-apart ribs extending across the base, the ends of each rib being spaced a short distance from the nearest wall, trough areas between and around said scraper members and between said scraper members and said walls to allow water to flow between said scraper members and reach said walls, and water-directing means formed through each straight wall, said water directing means being located between the corners defined by the junctions of successively adjacent straight walls, said water-directing means positioned for alignment with the water-directing means of adjacent connected tiles for directing water out of the tile to adjacent tiles when the water reaches a certain level on the top surface of the base.
Claim 2
Dependent Claim
225 words
A tile having a flat imperforate base with a top surface and a shape defined by straight sides, said tile comprising low straight walls protruding from said top surface along each side of the base, said wall forming the entire perimeter of the base to hold water on the base, means for use in removably connecting the tile to adjacent identical tiles to form a mat with the outside surface of a straight wall of the tile abutting the outside surfaces of the straight walls of adjacent tiles, scraper members upstanding from and uniformly distributed over said top surface within the confines of said wall, the scraper members comprising a series of spaced-apart ribs extending across the base, the ends of each rib being spaced a short distance from the nearest wall, trough areas between and around said scraper members and between said scraper members and said walls to allow water to flow between said scraper members and reach said walls, and water-directing means formed through each straight wall, said water directing means being located between the corners defined by the junctions of successively adjacent straight walls, said water-directing means positioned for alignment with the water-directing means of adjacent connected tiles for directing water out of the tile to adjacent tiles when the water reaches a certain level on the top surface of the base.
Claim 3
Dependent Claim
14 words
A tile as claimed in claim 1 wherein the tile is square and flexible.
Claim 4
Dependent Claim
15 words
A tile as claimed in claim 1 wherein the ribs extend diagonally to the walls.
Claim 5
Dependent Claim
26 words
A tile as claimed in claim 1 wherein the water directing means comprises at least one channel in the top of each wall of the tile.
Claim 6
Dependent Claim
24 words
A tile as claimed in claim 4 wherein one channel is provided in the top of each wall near each end of the wall.
Claim 7
Dependent Claim
51 words
A tile as claimed in claim 1 wherein the means for use in connecting the tile to adjacent tiles comprises female connecting means on the outer surface of two adjacent walls of the tile and male connecting means on the outer surface of the other two adjacent walls of the tile.
Claim 8
Dependent Claim
43 words
A tile as claimed in claim 6 wherein the female connecting means on each wall comprises two spaced-apart, inwardly directed slots, and the male connecting means on each wall comprises two spaced-apart outwardly directed projections shaped and positioned to mate with the slots.
Claim 9
Dependent Claim
19 words
A mat made from a plurality of individual identical tiles, each tile in accordance with claims 1 or 7.
Claim 10
Dependent Claim
54 words
A mat as claimed in claim 8 wherein the means on each tile for use in connecting it to an adjacent tile comprises female connecting means on the outer surface of two adjacent walls of the tile, and male connecting means on the outer surface of the other two adjacent walls of the tile.
Claim 11
Dependent Claim
53 words
A mat as claimed in claim 8 including edging strips about the outer periphery of the mat for retaining water in the mat, each edging strip having means on its inner side for use in connecting each strip to the tiles defining the outer edge of the mat, and a smooth outer side.
